This article discusses the use of the ESP32’s GPIO as an analog signal output through the 8-bit DAC module of the ESP32 microcontroller. In this article, we use Cosine wave generation to output the analog signal of the microcontroller through the speaker and show the waveform obtained from the oscilloscope display. The experimental board is still used as shown in Figure 1.
